Subject: 16-bit and 24-bit Floating-point

I read recently that ATI has 16, 24 and 32 bit floating point implemented on
its R300 graphics card. Obviously, there's an IEEE standard format for
32-bit, 64-bit and 128-bit floating point, but I don't know about any 16 or
24 bit formats. Do you know how ATI has allocated the bits as far as
exponent and mantissa?

With papers at SIGGRAPH on using GPU's as stream processors for ray-tracing,
and articles like
it looks like GPU's are an attractive platform for accelerating
numerically-intensive computations.

Subject: Special Year in Approximation Theory at Vanderbilt

Dear Colleagues,

To celebrate the recent founding of the Center for Constructive Approximation
at Vanderbilt University, we are organizing a Special Year in Approximation
Theory. The year will begin with a conference in May, 2003, and will end with
second conference in May, 2004. For more on the conferences, see below.

In addition to the conferences, we plan to organize workshops in several areas
of Approximation Theory. Details will be forthcoming. Moreover, we hope to
have as many short-term and long-term visitors as possible during the special
year. Please let us know if you are interested in such a visit. The program
for the Special Year is now in the planning stage and will be posted on the
Center website in the near future.

International Conference on

Our aim is to bring together researchers from diverse areas of approximation
theory, to stimulate international collaboration, and to promote interaction
and the exchange of ideas. We welcome the participation of both pure and
applied mathematicians working in approximation theory from all around the
world. We especially encourage young mathematicians and graduate students to

The topics of interest include, but are not limited to:

Abstract approximation
Approximation with constraints
Classical approximation
Complex approximation
Extremal problems
Interpolation and smoothing
Curves and surfaces
Multiresolution analysis
Nonlinear approximation
Orthogonal polynomials
Radial basis functions
Shift-invariant spaces
Subdivision and refinable functions
Image and signal processing

We invite you to contribute a talk in any area of approximation theory and
its applications. The duration of contributed talks will depend on the
number of participants and will be announced later. We expect to publish a
proceedings containing survey papers by the invited speakers and refereed
contributed papers. We are currently applying for funding to be able to
partially support the expenses of graduate students and other mathematicians
without support.

May 19-22, 2004

This conference is the eleventh in the well-established series of "Texas
meetings in Approximation Theory" (the previous two meetings were in
St. Louis, 2001, and Nashville, 1998). We will provide more information
about this event at a later date.

Subject: Conference at INRIA on Computer Vision and Computer Graphics

Computer Vision / Computer Graphics
Collaboration for
Model-based Imaging, Rendering, image Analysis and
Graphical special Effects (MIRAGE 2003)
10-12 March 2003, INRIA Rocquencourt, France

MIRAGE 2003 is designed as a very peculiar conference in the field of
Information Technology: it is dedicated to computer vision and
computer graphics collaboration studied as a tool for the production
of mirages of the reality. In the domain of computer vision, this
collaboration may take the form of model-based approaches with
feedback, as models are essential to process, analyze, understand and
generate complex still and animated images in a stable manner. Such
models must be comprehensive and their parameters updated according to
the difference between the expectation (real image) and the
synthesized results. In the computer graphics domain, a special
emphasis will be set upon techniques using real images as input for
realistic rendering, visualization and special effects.

MIRAGE 2003 is going to be an international conference where authors
are encouraged to submit papers on theoretical, computational,
experimental and industrial aspects of model-based image analysis and
synthesis. MIRAGE'2003 will be held in the new conference room of the
INRIA Rocquencourt research centre on March 10-12, 2003.

Topics include (but are not limited to)

* Model-based imaging and analysis
* Model-based vision approaches
* Model-based indexing and database retrieval
* Model-based object tracking in image sequences
* Image-based rendering and inverse rendering techniques
* New trends in model-based (and intrinsic) video compression techniques
* Virtual and augmented reality
* Generation of special effects
* Model-based evaluation of computer vision techniques, Image quality
* Applications
o Human-computer interaction, haptics
o Virtual prototyping
o Post-production, computer animation
o Multimedia applications (including face and gesture recognition),
multimedia databases
o Military applications
o Medical and biomedical applications
o Applications of fractals and multifractals

Subject: Conference in Vancouver on Computational Fluid Dynamics

CFD 2003
Vancouver, BC
May 28-30, 2003

Sponsored by the Societe canadienne de CFD Society of Canada



>From its origins as a tool primarily for use in aerodynamics, usage of
computational fluid dynamics has spread to a wide range of other fields,
such as biofluid mechanics, geophysics, atmospheric flows, and so
on. Each subspecialty has made its own advances on the state of the art,
but these advances do not necessarily propagate to other application
areas. This year's conference seeks to build from our historical solid
base in "traditional" applications of CFD to also include users in other
areas, laying the groundwork for future cooperation and collaboration.
Contributions from all sectors are solicited, across the full spectrum
of CFD research and applications.


The format of the conference will be similar to that in past
years, including (in addition to contributed papers)

* Four keynote lectures (topics and speakers TBA)
* Hardware and software vendor exhibits
* Code validation challenge
* Student paper competition
* Short course (topic TBA)
* Reception and banquet

The official languages for CFD 2003 will be English and French.
Papers and presentations will be accepted in either language.

Papers will be accepted on the basis of reviewed abstracts,
which should be between 500 and 1000 words in length. Figures
and tables can be added. Deadline for submission of abstracts
is December 16, 2002. Submissions can be made either by
hardcopy or electronically through email attachment (PDF
or Postscript format, please), and should include the author
name(s), affiliation and email contact information. Please

Subject: Research Position at Heriot Watt University

The Heriot-Watt Uncertainty project is an industry funded consortium at the
Institute of Petroleum Engineering at Heriot-Watt University. The Institute
of Petroleum Engineering has been ranked 5* in both the 1996 and 2001
Research Assessment Exercises, and is internationally recognised for the
quality of its research.
The goal of the Uncertainty Project is to develop methods of quantifying the
uncertainty in predicting the performance of oil reservoirs. This
uncertainty arises both from our lack of knowledge of the detailed geology
of the reservoir and from our inability to solve the equations describing
flow of oil through the reservoir exactly. The work will involve
demonstration of the ideas developed on field problems.
A vacancy exists at postdoctoral level for a highly motivated individual to
join the group. You must have a PhD and should have excellent
numerical/computational skills, and a background in applied mathematics,
statistics, physics or engineering. Knowledge of the oil industry,
geostatistical methods, and demonstrated programming skills will be an
advantage. The post is available for two years.
For additional information please contact Prof M A Christie ( <>).
For application details please contact the Personnel Office, Heriot-Watt
